DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape attaching device with a tab for automatically attaching an adhesive tape having a non-adhesive tab portion to an object moving in a predetermined direction. This tape attaching device with a tab can be used in an automatic packing machine such as a cardboard box.

[0002]

2. Description of the Related Art When an adhesive tape is adhered to an adherend such as a cardboard box for the purpose of packing or sealing, for example, the adhesive tape is adhered in advance in order to facilitate removal of the adhered adhesive tape when opening. It is known to form a non-adhesive tab portion on a surface. The preforming method of such a tab portion is as follows.
The method is roughly divided into two methods: a method of attaching a tab film as another member to a desired portion of the adhesive tape, and a method of performing a partial non-adhesive process on the adhesive tape itself.

[0003] As an attaching device for automatically attaching an adhesive tape with tabs formed with tab portions by the former tab film attaching method to an adherend such as a cardboard box, for example, as disclosed in US Patent No. 4,238,269, it is disclosed. There is known a type in which a tab attaching device having a movable cassette for holding a plurality of tab films is incorporated in a known adhesive tape attaching device. This kind of tabbed tape applying apparatus, as shown schematically in FIG. 1 5, the adhesive tape 2 is fed from the tape supply roll 1 for storing adhesive tape in roll form to tape applying a desired position of the bonding surface And a movable tab cassette 4 to which a tab film 3 is attached.
The tab cassette 4 stacks and holds a plurality of tab films 3 cut and formed in a predetermined shape and size from a continuous body in advance. In the tape affixing section, an adherend 5 such as a cardboard box moves along a predetermined track, and
Is applied to the adherend 5 by the tape application roller 6. The adhesive tape 2 is automatically sent out from the tape supply roll 1 as the adherend 5 moves. A sensor 7 for detecting the passage of the adherend 5 at the rear end in the moving direction is arranged at a predetermined position on the tape attaching portion,
In response to the detection of the passage of the rear end portion, the tab cassette 4 is quickly moved in the direction of the adhesive tape 2 by cassette driving means (not shown), and the tab film 3 is attached to the adhesive tape 2 in a stamp manner. The adhesive tape 2 to which the tab film 3 is attached is cut together with the tab film 3 at a substantially central position of the tab film 3 by the cutter blade 8 at the tape attaching portion.
Therefore, the adhesive tape 2 to which the half-cut tab films 3 are attached is attached to both ends of the adherend 5 in the longitudinal direction.

As the latter method of partially non-adhesive processing, the production of an adhesive tape without applying an adhesive to the side edges has been proposed.
It is disclosed in Japanese Patent Application Publication No. Further, a dispenser for a tape with a tab using a partial non-adhesive processing method is disclosed in Japanese Utility Model Laid-Open No. 63-37070. This tape dispenser is provided with a folding guide of a side edge portion of the adhesive tape, and when the adhesive tape is pulled out, the side edge portion is automatically folded in the direction of the adhesive surface by the folding guide, and the non-adhesive surface of itself. A tab portion is formed by the (back surface).

[0005]

A conventional tape affixing apparatus with a tab using the above described method for attaching a tab film has a tab cassette capable of accommodating a predetermined number of tab films 3 cut and formed in a predetermined shape and size in advance. Since 4 is used, the number of adherends that can be adhered is necessarily limited when performing continuous application to a large number of adherends 5 that move continuously. Frequent replacement of the tub cassette 4 is required to replenish the tub film 3, thereby preventing continuous operation of the apparatus. When the length of the tab film 3 is changed in accordance with the size of the adherend 5, etc., it is necessary to replace the tab film 3 with a tab cassette accommodating a tab film having a different size. Furthermore, since the tab film 3 is attached to the adhesive tape 2 in a stamping manner, the feed speed of the adhesive tape 2, that is, the feed speed of the adherend 5 must necessarily be reduced. Has become a bottleneck. In addition, due to the preparation work for cutting and forming a large number of tab films 3, the cost related to tab attachment increases.

Further, known adhesive tapes having side edges to which no adhesive is applied increase material costs and complicate inventory management. Therefore, tape sticking of an automatic packing machine which requires an extremely large amount of adhesive tape is required. Not suitable for use in equipment. Further, the above-mentioned tape dispenser is advantageous in cost because an ordinary adhesive tape can be used and a tab film is not used.However, since the tension of the adhesive tape in the bending guide portion is insufficient, for example, an automatic packing machine is used. When applying to the tape sticking device of the above, the tape side edge bending function of the bending guide cannot follow the high tape feed speed, and the width of the tab portion becomes uneven, and the tab portion becomes loose or wrinkled.

A signal is sent to the control device 105 of the second cylinder device 100 to set the start timing of the first cylinder device 100. After the front surface 16 a of the box 16 has passed the sensor 118, the adhesive tape 26 is
Is attached to the box 16 and the time T ₁ until it is cut is
It is calculated from the position of the sensor 118, the length of the box 16, and the transport speed of the belt conveyor 22. Further, after the tab film 30 is attached to the adhesive tape 26, the adhesive tape 2
The time T ₂ before the cutting of the belt conveyor 6 is cut off by the belt conveyor 22.
Is determined only by the transport speed. So timer 120
By setting a time T = T ₁ −T ₂ from the detection of the passage of the box 16 to the activation of the operation of the tab attaching device 32, the length of the box 16 (L <S + s) is set. The tab film 30 can be attached to a desired position of the adhesive tape 26.

When L = S + s, the above L <S +
The operation timing is set in the same manner as in the case of s.
The cutting of 6 and the attachment of the tab film 30 by the tab attachment device 32 are synchronized, and the attachment of the tab film 30 having a desired length becomes difficult due to the stop of the adhesive tape 26. Therefore, by installing a bypass roller (not shown) between the cutter blade 40 of the tape application head 24 and each of the application rollers 74 and 76 of the tab application device 32, and by increasing the distance S, the case where L <S + s is satisfied. The same operation becomes possible.

Further, according to the present invention, the tab film is sent out at the same speed by attaching the tab film to the adhesive tape fed at a predetermined speed, so that the operation time interval between the attachment and cutting of the tab film by the tab attaching head is changed. By doing so, the length of the tab film to be attached can be variously set. In the first embodiment shown in FIG. 1, a timer 122 is provided in the control device 105 of the tab attaching device 32 as a second time setting means for setting the operation time. The timer 122 sets the time required for one reciprocating operation of the linear motion rod 102 of the first cylinder device 100, that is, the pull-in operation of the linear motion rod 102 from the initial state in which the upper attachment roller 74 and the cutting edge of the cutter blade 78 are arranged close to each other. As a result, the cutter blade 78 is pulled upward, and at the same time, the upper attachment roller 74 is moved downward to collide with the lower attachment roller 76, and the tab rod 30 is attached to the adhesive tape 26. Returning to the state, the operation time until the cutter blade 78 cuts the tab film 30 is variously set, and a signal is sent to the control device 105. In this embodiment, since the adhesive tape 26 is fed at a speed equal to the transport speed of the belt conveyor 22,
The setting of the operation time by the timer 122 determines the length of the tab film 30.

In the present invention, when the adhesive tape and the tab film are cut at one time, the tape is cut at a substantially central position of the tab film, so that the rear end of one adhesive tape and the front end of the next adhesive tape are substantially separated. An equal length of tab film is applied. Therefore, in the first embodiment, the operation error of the cutting of the adhesive tape by the tape attaching head specified by the first time setting means (timer 120) is absorbed by the second time setting means (timer 122). It becomes possible.

The overall operation of the tab-attached tape applying apparatus 12 having the above configuration will be supplementarily described below with reference to FIG. First, as an initial state, the adhesive tape 26 pulled out from the tape supply roll 28 passes through the tab attaching device 32 as described above, and the leading end of the adhesive tape 26 is

Detects the passage of the front surface 16 a or the rear surface 16 c of the box 16, and the tab film 30 is attached to the adhesive tape 26 by the tab attaching head 70 of the tab attaching device 32 according to the setting of the timer 120. At this time, the adhesive tape 26 is separated from the box 16 by the attaching roller 36 of the tape attaching head 24.
The tape attaching head 7 moves at a predetermined speed while being adhered to the adhesive tape 26 while moving.
Then, the attachment and cutting operations of the tab film 30 are performed. One piece of the tab film 30 attached to the adhesive tape 26 advances with the adhesive tape 26 as the box 16 advances, and is cut by the cutter blade 40 of the tape attaching head 24 along with the adhesive tape 26 at a substantially central position.
In this way, the adhesive tape 26 having the tab film 30 attached to one end is attached to the box 16. Next box 16
